My question is, wheather it is possible to find analytical form of
equation (EC) describing crossing of these two (F1 and F2) functions.
Another thing is, if I have this equation (EC) is it possible to plot
surfaces of F1 and F2, only up to values less or equal to this
function (EC)? (So that plotted are only lower part of these functions
(F1&F2))
I hope it is understandable
